Hiring for technical roles:
Engineering (13 roles): Backend, Full Stack, Platform, SRE, Analytics, Data Engineering, Security
Research (8 roles): Research Scientists, Research Engineers, HPC Engineers, Research Tooling
Product (3 roles): Product Managers, Product Designers
Agentic AI (2 roles): Platform Engineers, Forward Deployed Engineers

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate biological discovery and drug development.
We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.
We are hiring for three core roles:
1. Senior TypeScript Engineer (Desktop Platform / SDK): This is not a dashboard or a simple web GUI. You will build the architecture of our Desktop Platform—a high-performance local application that acts as the "OS" interface. You will deal with complex state management, massive data throughput, and bridge directly with our high-performance Rust data layer. We need someone who treats the browser engine as a runtime for heavy applications, not just for websites.
2. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.
3. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing production blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology (Builder profile, not just analyst).
The Offer:
Comp: Top-tier EU salaries (~€90k - €120k).
Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).
The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.
Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."
Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).
Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.
Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.

Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.
Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).
We aim to hire you in February or March ultimately.
